How it works Instead of setting individual ad set budgets, you set one overarching campaign budget. This budget has flexibility to spend more on ad sets with the best opportunities, and less on underperforming ad sets. The amount you set can apply to each day the campaign runs ( daily budget ) , or over the lifetime of the campaign ( lifetime budget ).
